UNITED STATES JACOB LUTHER, OF BUCHANAN, MICHIGAN, ASSIGNOR OF ONE-HALF HIS PATENT Orrron.

RIGHT TO RICHARDS & FOX, OF SAME PLACE.

IMPROVEMENT IN CARPET-STRETCHERS.

Specification forming part of Letters Patent No. 144,464, dated November 11, 1873; application filed July 25, 1873. I

To all whom it may concern:

Be it known that I, JACOB LUTHER, of Buchanan, in the county of Berrien and State of Michigan, have invented certain Improvements in Oarpet-Stretchers, of which the fol- This invention has for its object to furnish a carpet-stretcher by means of which a considerable breadth may be stretched and held at once while being tacked down and to this I end it consists in a cylindrical roller armed with studs to engage with the fabric, and an axis at each end, with which engages a pair of hooked dogs adapted to be driven into the floor at the side of the room, one of the dogs hava pawl pivotedto it to engage with a ratchet on the end of the roller, to prevent it from turning back when a strain is got on the carpet by rotating the roller by a hand-spike i11- serted in one of the sockets in its middle.

In the accompanying perspective view, A represents aroller of wood or metal, provided with a series of studs, 11, on its periphery, having also a series of sockets, b, for the reception of a lever, B. At each end is an axis, 0, with which may engage the hook at the end of a metallic dog, 0, whose other end is sharpened to drive into the floor close to the base-board. One of these dogs has pivoted to it a pawl, d,

which engages with a ratchet, e, on the end of the roller.

In operation, the carpet is spread on-the floor and tacked down in one corner. At the next corner of the room the dogs are driven into the floor close to the base-board; the roller is then brought over and the hooks of the dogs sprung over the axes; the pawl is then engaged with the ratchet, and the lever inserted in one of the roller-sockets; then, by moving the lever in the direction of the arrow, the

carpet will be stretched with great power, the

ratchet preventing it from slacking back by arrestin g the reverse movement of the roller. In the full-size stretcher-there is room between the roller and the wall for a person to stand or kneel while stretching; then step.

the studded roller A, having handle B and ratchet e, in combination with dog O and pawl 01, as described.
